Our lifetime guarantee covers the tool body and shank. The blades are

covered for 90 days from the date of purchase for breakage under normal

working conditions. Blades will dull faster cutting hardwoods vs

softwoods (peeled or unpeeled). Soil and other abrasive substances will

reduce blade life and is not covered under this warranty. When making a

claim, you must show proof of purchase from an authorized distributor.

This is valid only to the original buyer, and not for tools sold secondhand,

used, or sold “as is” to a second party.

What Voids Warranty

In order to keep our lifetime and 90 day warranty you must AVOID the

following actions:

●Operating the tool in a drill press or lathe (or any system other than

a hand-held drill)

●Running the tool into a nail or foreign object

●Altering or misusing the tool

About Your Product

Thank you for purchasing our Dual Blade - Radius Shoulder Tenon Cutter!

Lumberjack engineers, along with our craftsmen, have designed the

safest, easiest-to-use tenon cutters on the market. By combining old

world skills with 3D CAD modeling and CNC manufacturing, we have

created the ideal tenon cutter: straight tenons, smooth finish, precision

operation, and long life.

Dual-bladed tenon tools will cut a tenon in half the time of a single-bladed

tool. Wear is reduced by putting force of cutting across two blades

instead of one. The blades are stamped, heat treated and precision

ground to provide years of service if properly maintained. The Pro tools

are machined from a solid aluminum billet and the Home tools are made

of die-cast aluminum.

SAFETY

Before beginning any project, carefully read and follow ALL safety and

operational instructions for any tools or devices you will be using. Failure to do

so may cause physical harm to yourself or those around you. If you feel

uncomfortable using our tenon cutters or any other tool, STOP immediately.

Lumberjack Tools assumes no responsibility for injury caused to the operator,

bystander, or tools used in conjunction with the use or misuse of our tenon

cutters.

NEVER OPERATE POWER TOOLS UNDER THE INFLUENCE OF

DRUGS, ALCOHOL, OR ANY MEDICATIONS

ALWAYS WEAR SAFETY GLASSES, DUST MASK, AND ANY OTHER

PERSONAL PROTECTION ITEMS AS NEEDED

NEVER WEAR LOOSE ITEMS THAT COULD BE CAUGHT IN MOVING

PARTS. SECURE LOOSE OR LONG HAIR AWAY FROM AREA

WE STRONGLY RECOMMEND A SINGLE-SPEED, GEAR DRIVEN DRILL

WITH RPMS OF 500 OR LESS. EXCEEDING THESE RPMS MAY

RESULT IN DAMAGE TO THE TOOL

ALWAYS DISCONNECT POWER AND ALLOW DRILL TO COME TO A

COMPLETE STOP BEFORE INSTALLING, REMOVING, OR ADJUSTING

THE TOOL

NEVER APPLY BENDING FORCE (SIDE LOADING) TO THE TOOL. SIDE

LOADING COULD CAUSE THE SHANK TO FAIL, OR MAY RESULT IN

BLADE DAMAGE

ALWAYS SECURE THE LOG IN A VISE OR CLAMP PRIOR TO

STARTING YOUR DRILL. FAILURE TO DO SO MAY RESULT IN INJURY

ALWAYS HANDLE THE BLADES WITH EXTREME CARE! FAILURE TO

DO SO MAY RESULT IN SERIOUS INJURY

WHEN EXCESSIVE FORCE IS REQUIRED TO CUT, RE-SHARPEN OR

REPLACE THE BLADES. A SHARP TOOL IS A SAFE TOOL!

NEVER PUT HANDS OR ANY BODY PART INSIDE THE TOOL WHILE THE

BLADES ARE ATTACHED! DOING SO MAY CAUSE SERIOUS INJURY

Pro Series ONLY

Quick Stop Installation

●Install the quick stop pin through

the tool body

●Secure with the supplied acorn nut

●The length of the tenon is

determined by measuring from

the face of the tool to the bottom

of the Quick Stop Pin and

subtracting 3/4”

●In the image to the left, dimension

“X” - 3/4” = approximate length of

the tenon

Correct (smaller tenon) Correct (larger tenon) WRONG

The tenon diameter is variable based on the blade offset. Smaller offset

= smaller tenon, larger offset = larger tenon. 3/16” blade offset is a good

place to start, but you will want to test tenon fit in holes to achieve the

correct offset (we recommend writing the results down). DO NOT set the

blades beyond 5/16” or the blade edge will not contact the log and will

not cut.

comes in is slightly thicker than

●Remove a piece of box to use as a

quick spacer for blade setting

TIP

Determine tenon length before cutting

●The key is to have a gap

between the end of the

tenon and bottom of the

mortise hole

●This can be done by making

the tenon 1/8” to 1/4”

shorter than the mortise

WARNING: If the log comes loose or unclamped while cutting the

tenon, DO NOT drop the drill or try to grab the log! Stop the drill and

remove it from the end of the log. Re-secure the log, and resume

●Obtain the log you want to tenon

●Cut it to length and make sure the ends

are flat. If the ends are not even/flat, the

tenon will be crooked

●If the log diameter is

larger than the tool can

accept, taper the end

with a draw knife

●Secure the log in a vise, clamp,

or fixture with a “V” shaped

notch

●The Log Lock (LL1545) is a safe,

easy, economical way to clamp

logs, and is available on our

website

Cutting Tenons

ALWAYS unplug the drill before adjusting the blades or

adjusting the chuck

●Make sure the tool is square against the end of the log

before cutting

●If the tool is held at an angle the tenon will be cut angled

Cutting Tenons (cont.)

●Carefully install the tenon

cutter into an unplugged 1/2”

drill, and tighten it firmly. Use

the tee handle to tighten the

chuck

●Square up to the log so that

the cutter is flush against the

flat face of the log

●Apply body pressure by leaning

into the drill

●Pull the trigger to cut the tenon

●Wait until the drill comes to a

stop before removing the

cutter from the log

Additional Tips

●It takes time to master using

these tools

●Make a plan of what you want

to build before you begin

●Have a list of all tools and

materials you will need

●Do not over complicate your first

few projects

●Practice reading the natural twists

and defects in the wood

●Practice cutting tenons and using

the tools on scrap material

●Measure and mark the locations of all

holes before drilling

●Place the center of the bit on the

desired hole location

●Take care to hold the drill perpendicular

to the log

●Use a forstner bit (or spade bit) to drill

the hole

●Drill mortise between

1/3 and 1/2 of the log

diameter

●Do not drill more than

1/2 of the log

diameter unless a

specific project calls

for a deeper mortise

Maintenance

●Body

- Cleaning

○Keep the tenon cutter body clear of sap and other build-up

○Always remove the blades before cleaning

○Clean the tool with a solvent (such as mineral spirits)

●Blades

- Care

○Always wipe blades with a thin film of oil at the end of the day

to help prevent oxidation

- Cleaning

○Clean the blades with a solvent (such as mineral spirits) and

immediately apply a thin film of oil to prevent oxidation

- Sharpening

○Use a sharpening stone or file to re-sharpen the blades, then

clean the blades and apply a thin film of oil

●Shank

- Replacement

○If your shank breaks, we offer replacement shanks (see first

page for contact information)

○Turn the shank counter-clockwise to remove

○Turn the shank clockwise to install

WARNING: ALWAYS HANDLE THE BLADES WITH EXTREME CARE!

PROBLEM CAUSE SOLUTION

• Tool Skips off

to one side or

bounces around

• Log is larger than tool will

• Taper down the end of the

log with a draw knife

• Not enough pressure is being

applied • Lean into drill with body

• Not cutting log

• Log is larger than tool will

• Taper down the end of the

log with a draw knife

• Blades are slid too far back • Position blades so they are

back no further than 5/16"

• Blades are dull

• Not applying enough

pressure

• Sharpen blades

• Purchase new blades

• Lean into drill with body

• Takes too

much of a "bite"

• Aggressive cutting from dual

blades

• Remove one blade or

"shim" blade up to .020”

• Crooked Joint • Holding drill crooked while

cutting

• Position the drill square

against the log before cutting

• Drill stops or

cuts on small

diameter logs

but not larger

ones

• Using a variable speed drill

• Make sure you are using a

single-speed drill with low

RPMs

• Using a non-Milwaukee

brand drill

• We recommend purchasing

a Milwaukee brand hole hog

drill

• Spiral grooves

on the tenon

joint

• Lateral wobbling of the drill • Hold the drill as steady as

you can while cutting

• Removing the cutter while

drill is still spinning

• DO NOT remove the cutter

until the drill has come to a

complete stop
